numpy.rAnDom.rAnDint

这是使用的numpy模块中的随机函数,应该先导入这个模块: from numpy import *然后就可以使用你的random.rand(4,4)了。 不过,不建议这样导入,有可能与导入的其它模块产生冲突,建议: import numpy as npnp.random.rand(4,4)

import numpy as nprand = np.random.randint(0,2,(3,8))print(rand)[[1 1 0 0 1 0 1 0] [0 1 0 1 0 1 0 0] [0 0 1 0 0 1 0 0]]

from numpy import randomrandArray = random.random(size=(2,4))#输出#array([[0.93848018,0.42005976,0.81470729,0.98797783],[0.12242703,0...

randn是NumPy中的一个函数。这里有文档:http://docs.scipy.org/doc/numpy/reference/generated/numpy.random.randn.html

from numpy import randomrandArray = random.random(size=(2,4))#输出#array([[0.93848018,0.42005976,0.81470729,0.98797783],[0.12242703,0...

print int(time.time()); print '%s%s-%s%s'%(IMAGE_BAKUP,int(time.time()),random.randint(0,99), _CONTENT_TYPES[_CONTENT_TYPES]) 运行后出错...
